摘要： 单色光波正入射到任意取向的双轴晶体上的情况,求得了双轴晶体中偏振光的传播方向及相应入射分量的折反系数的计算公式,并得出了偏振光的振动方向恒在折射面内、两折射面恒正交的重要结论。最后就NaNO2晶体的相应计算数据,画出晶体中偏振光出射点随晶体取向而变化的轨迹图及反射系数变化图予以讨论。这些结果为应用新的方法测量双轴晶体光学参量提供了可能性。

Abstract： In this paper, it is discussed that when monochromatic light incident normally on an arbitrarly making directional biaxial crystal. The formulas can be deduced for propagating directions of polarized light and the transmittance—reflectances of incident components. An important conclusion isobtained that directions of polarization are always on the refractive planes and the two refractive planes are perpendicular with ecch other. And finally, the numerical results are plotted in curvilineal diagrams for NaNO2, it is seen that the changes of the emergent points of polarized light and that of the reflectances are obvious as the crystal making directions change. These results offer a new possibility for determination of crystal optical constants.
